Rotring 800 mechanical pencil. Heavy metal hexagonal barrel with cylindrical knurled grip. The 800 features a retractable tip - twist the knurled control above the clip to extend or retract the whole writing tip, making the 800 exceptionally pocket-safe and less susceptible to accidental sleeve damage. 4mm fixed sleeve. Eraser under the push-button. Matt silver finish. This is probably the ultimate drafting pencil in our range. 144mm long with tip extended, 133mm long tip retracted. 25g.
